I’m using ActiveScaffold.

In the file house\_helper.rb I have written the code:

def house\_form\_column(record, input\_name)  
…  
list = House.find(:all, :include =\> ‘city’)  
new\_list=…  
…  
list do |element|  
if record = element.name  
selec=element.id  
end  
end  
select\_tag ‘X’,options\_for\_select(new\_list, selected=selec),  
{:multiple =\> false}  
…

to visualize a combobox with some data. The information is visualised  
correctly but I can’t select a value in the combobox, it doesn’t work.
